The plugins that this change takes advantage of will only stream free
software, as it doesn't depend on gst-plugins-ugly or gst-plugins-bad.

I can't give a definitive list of formats, but the GStreamer plugins
this change will take advantage of only support free formats, consist
entirely of free code, and have a policy against implementing DRM.

GStreamer itself is a framework that is 100% free (as in freedom)
software.  There are proprietary plugins that implement DRM, but they
are separate from GStreamer itself and the base and good plugins, and
Emacs will not use them even if present on a user's system.

People seem to want that in Emacs.
